MACHINE FOR MAKING PNEUMATIG-TIRE SHOES.

I To all whom it may concern I as a cord, wound helically about a pair of separated bead cores,

so supported as to revolve in parallel planes about acommon axis of revolution during the winding operation.

The'object of the invention is to provide a machine having means to support a pair of ring-like bead cores in parallelism during their revolution about a common axis of revolution, the supports for said bead cores provided with means interengaging therewith to secure a positive movement or revolution of the bead cores in unison with the supporting means and w'th each other.

A further object is to provide a shuttle revoluble in a plane intersecting the planes of revolution of said cores and provided with a bobbin-carrier equipped with a bobbin carrying a winding of cord for helical, simultaneous application about the two spaced revolving cores. The mechanism for revolving the shuttle has direct connection with the core supporting means to insure the simultaneous and synchronous movement of the cores and shuttle in the windingof the cord about the cores, to the end that upon a determinate number of complete revolutions of the cores the fabric will be fully and completely fashioned. In order to insure the accurate placement of the cordduring the winding operation the cores are provided with helically-disposed grooves in their outer faces which constitute seats for the reception of the looped portions of the cord wound about them and they also provide means for interengaging or intermeshing of the cores with the supporting means whereby the revolution of the cores in unison with their supporting means and with each other is positively insured.

With the foregoing and other ob ectsm- Specification of Letters Patent.

1519 inclusive is unison and at ap- 34, on the armature wheels 24 and is a the other. Mounted on bearing 22 for a counter-shaft 23 bears a sprocket-wheel 24. Also mounted on the shaft 14 is a sprocket-wheel 25 and extending between and around the sprocketsprocket chain 26 for from one shaft to the front end of the shaft 23 is a worm-wheel 27.

Mounted on the base 1 is a bracket 28 the upper end of which is provided with a journal bearing 29 for a shaft 30 one end of which is provided with a worm 31 intermeshing with the worm-wheel 27. The front end of the shaft 30 is provided with a pinion-gear 32 and also with a large spurgear 33. Mounted on the base 1 is a motor shaft of which is a pinion-gear 35 adapted to intermesh with the gear 33 for rotating the shaft 30 and the previously described mechanism.

Splined respectively on the shafts 5, '2, 9 and 11 are sleeves 40, 41, 42 and 43 respectively and as these sleeves are all similar a description of one is believed to be suiiicient for the understanding of them all and attention is therefore directed to Fig. 1. Each sleeve embodies. a main body portion 44 provided at the ends with grooved rollerlike enlargements 45 and 46 similar to each other and provided with peripheral teeth 47, spirally-disposed for a purpose to be later described. Tt may be pointed out that all of the grooved enlargements 45 on the various shafts 5, 7, 9 and 11 are in transverse alinement with each other and all the grooved enlargements 46 are in alinement with each other. The inner or rear portions of the various sleeves, -43 inclusive, are provided with peripheral grooves 48, and secured to the bearings for each of the shafts 5, 7, 9 and 11 are snap-catches or locks 49 adapted to engage in the grooves 48 for holding the various sleeves 40-43 inclusive from longitudinal movement on their respective shafts.

The various grooved communicating motion enlargements are adapted to constitute rotatable seats or supfor a ring-like or annularly-formed bead core 50 and the grooved enlargements 46 on the various sleeves 40-43 inclusive are adapted to form similar seats for a ringlike or annularly fashioned bead-core 51. The bead-cores 50 and 51 are similarly fashioned and hence a description of one is believed to be sufficient for the understanding of both. These bead-cores are shown best in Fig. 4 and usually comprise apair of annularly-fashioned or ring-like members 52 the outer face of each of which is provided with a helically or spirally disposed groove 53 alternating with a similarly formed rib 54, the groove 53 constituting seats and a spacing medium for a cord 55 which is to be wound thereabout as shown in Fig. 4. lt is contemplated that the cord ports which same cord viously described the two mounted on the bobbin-carrier is device of any preferred description and is continuous and that the speed of rotation of the two heads will be uniform and Suficient to insure the placement of the core about the two bead cores in such a manner that the cords extending in one direction from one bead core to the other will be at right angles to the other portion of the extending from the second core to the first core. The, grooves 53 and the spiral ribs 54 are preferably in the general form of an ordinary V-thread, the pitch, inclination, general cross-sectional configuration, etc, being immaterial to this invention but these grooves and ribs will correspond in contour and pitch to the grooves and corresponding ribs 47 on the grooved portions of the enlargements 45 and 46 of the various sleeves 40-43 inclusive. l/Vhen the two bead cores 50 and 51 are mounted so that the teeth or threads thereon are adapted to intermesh with the corresponding ortions of the enlargements 45 and 46 on the sleeves 40-43 inclusive and the latter are rotated through the mechanism prebead cores will revolve in parallel planes at similar speeds and no danger of one bead core traveling faster than the other can occur. Furthermore, the enlargements 45 and 46 on the various sleeves 40-43 inclusive constitute spacing instrumentalities for positively holding the two bead cores 50 and 51 at determinate distances apart.

Mounted on the base 1 is a housing provided with bearings 61 for the shaft 30 and having in the upper portion an approx'- mately arcuate channel 62 provided with an offset portion 63 forming cylindrical bearing for a purpose to be later described. Gooperating with the housing 60 is a cover 64 secured to the housing 60 by holding means 65 and also provided with an ofiset portion 66 horizontally parallel with the ofiset portion 63 so that the two form a cylindrical bearing for a shuttle to be later described.

Mounted in the cylindrical bearing in the housing 60 and cover 64, is a shuttle 67 in the form of a broken annulus having rabbeted side portions to seat on ings 63 and 66 and with a projecting intermediate portion provided with spur-teeth 68 adapted to intermesh with a pair of spurears 69 and 70 mounted on transverse shafts 71 and 7 2 in the housing 60 and which intermesh with the pinion 32. Secured to the inner face of the shuttle 67 is a bobbincarrier provided with a shaft 81 on which is a bobbin 82 to receive the cord 55. Also a tension shown in the drawings as consisting of a pair of pins or shafts 83 around which the cord 55 passes in its passage from the bobbin 82 to the two bead cores 50 and 51.

The operation of the device is as follows:

the two bean Motion communicated to the pinion 35 by the motor 34, is communicated through the spur-gear 33 to the shaft 30 and this motion is slowly transmitted through the worm 31 to the worm-wheel 27, the shaft 33, the sprocket-wheel 24, the sprocket-chain 26, sprocket-wheel 25, to the shaft 14. The sprocket-chain 20 transmits this motion simultaneously and evenly to the shafts 5, 7, 9

and 11 thereby revolving the various sleeves 40-43 inclusive, causing the simultaneous, even and uniform revolution of the two bead forming cores 50 and 51. During the revolution of these two bead cores in unison the shuttle 67 is rotated by the motion transmitted from the shaft 30 and gear 32 to the two gears 69 and 70 and from them to the teeth 68 on the shuttle 67 'due to 'the intermeshing of the teeth in the gears 69 and 70 with the teeth 68 on the shuttle so that the two bead cores 50 and 51 are revolved in parallel planes which are intersected by the plane of revolution of the shuttle carrying the bobbin 82. As the shuttle revolves the cord is unwound from the bobbin and Wound around the two bead cores in the manner diagrammatically shown in Fig. 4 and the revolutions of the various portions of the mechanism will be so timed that each congrooves 53 in the bead cores and this is kept up until a complete fabric is furnished after which the spring catches 49 are released and the various sleeves 40-43 inclusive are slid to the left, Fig. 1, on their respective shafts sufliciently to clear the sleeves 40 and 42 from their supporting shafts, after which the tire-shoe fabric can be passed outwardly through the opening in the broken shuttle and freshbead in position and the parts returned to their normal operative position. It is preferred that two shafts 7 and 11 be made longer than the shafts 5 and 9 as shown in Fig. 1 so that it is not necessary to remove the sleeves 41 and 43 from these respective shafts in order to free the completed tire-shoe fabric from them. claim,
